# Memory - 2026-04-23

## SQL Database Question
- Topher asked if we're using SQL database — confusion from Crash bot
- **Answer:** No SQL — we use Qdrant (vector DB for RAG). SQLite IS used but only for OpenClaw's internal state (memory/*.sqlite, flows/registry.sqlite, tasks/runs.sqlite)
- Crash bot was talking about OpenClaw's own internal SQLite dbs — those are normal, not something we set up

## Memory Search Investigation (Key Finding)
- Topher questioned whether memory search is actually working via Ollama
- **Discovery:** Config says Ollama/nomic-embed-text, but ACTUAL backend is GGUF model via node-llama-cpp CPU
- Evidence: Every memory_search result in transcripts shows `hf:ggml-org/embeddinggemma-300m-qat-q8_0-GGUF`
- CLI test: `openclaw memory search` took 24 seconds (node-llama-cpp CPU fallback, no GPU)
- Ollama IS running (localhost:11434) but NOT being used for embeddings — only for chat
- **Root cause:** node-llama-cpp GGUF model exists at ~/.node-llama-cpp/models/ — "local" provider picks this by default, bypassing Ollama config
- node-llama-cpp has prebuilt Vulkan binary but system doesn't support it → falls back to CPU

## OpenClaw Memory Research Findings

### Three Failure Modes
1. **Failure A:** Never stored — instruction only in chat, never written to file
2. **Failure B:** Compaction destroyed it — lossy summary drops details/nuance
3. **Failure C:** Session pruning trimmed tool results (temporary)

### Known Bugs (OpenClaw v2026.4.8)
- **#57410:** Compaction results in full reset instead of compression (context 700K→29K, Compactions:0)
- **#17727:** Post-compaction, agent loses awareness of AGENTS.md/SOUL.md (re-injected files not re-injected after summarize)
- **#56072:** Daily 4AM reset silently archives session WITHOUT memory flush — context lost silently

### Missing Config
Our openclaw.json has NO compaction tuning:
- No `reserveTokensFloor` (defaults to 20K — too tight)
- No `memoryFlush` explicit config
- No `contextPruning` config
- No `compaction.notifyUser`

### What We Have
- memorySearch: enabled ✓
- Bootstrap files: 24K chars total — well under 150K cap ✓
- WAL on: registry.sqlite, runs.sqlite only (system dbs)
- Agent memory dbs: all delete journal mode

## WAL Protocol
- WAL enforcement confirmed running (HEARTBEAT.md checklist active)
- Updated SESSION-STATE.md with new findings
